KNIFE-SHARPENER.

Speccaton of Letters Patent.

Patented Dec. 7, 1909.

Application filed February 4, 1909. Serial No. 476,042.

To all whom it may concern:

Be it known that I, Moens L. HAwxs, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Knife-Sharpeners;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to knife sharpening devices and particularly tothat type which employ a cutting or shaving steel and a guiding portionor body.

The object of the present invention is to improve upon former patentstaken out by me and to render the device more serviceable and at thesame time cheap in its construction.

A still further object of the invention is the provision of meanswhereby the guiding means for the scissor blades may be used for openingbeverage bottles.

With the foregoing and other objects in view, the invention consists ofcertain novel features of construction, combination and arrangement ofparts as will be more fully described and particularly pointed out inthe appended claim.

In the accompany drawings, Figure 1 is a top plan view of the inventionshowing a can opener attachment applied to the handle; Fig. 2 is a rearview of the device shown in Fig. 1; Fig. 3 is a transverse sectionalview on the line 3 3 of Fig. 1; Fig. 4 is a transverse section on theline 4-4 of Fig. 1; Fig. 5 is a perspective view of the clamping plateremoved from the device; Fig. 6 is a plan view of the device without thecan opener attachment.

Referring more especially to the drawings, 1 represents the body of thedevice which is preferably constructed of heavy wire having the oppositelegs thereof, intermediate their ends, convergent so as to form abeveled bearing surface 2 which is arranged adjacent the steel 3. Theopposite end of this body is extended out into connected parallelportions 4 which form a handle for the device and upon which Ipreferably mount the component parts 5 and 6 of a can opener.

Adjacent the bearing portion 2, the legs of the body are extended orbulged out, as at 7, in order to provide the double bearing points a andb for the steel and prevent the latter from engaging the legs throughoutits length. The outer ends of the legs are preferably turned outwardlyand upwardly into the form of hooks 8 which are beveled at 9 to formengaging edges 10. These hooks while primarily formed to make bearingsurfaces 11 for the guidance of the scissor blades and heavierinstruments, such as cleavers, and the like, they are admirably adaptedto remove the caps of bottle closures.

The legs of the body at the bearing points a and b are arranged insubstantially parallel relation and the cutting steel 3 which is used,being triangular in shape, lies in between the legs with its upper edgesoverlapping the same and its lower conical edge projecting therethrough,as shown in Fig. 4.

In order to hold the steel in position, I provide a clamping plate 12which is provided with a central raised ridge 13 forming a channel 14for the reception of a locking pin 15. The plate 12 is provided withsubstantially V-shaped notches 16 in its ends so that when the ends arebent around the legs of the body, the edges of the notches 16 will beclosely arranged, as shown in Fig. 2. The wedge 15 lies onV top of thecutting steel and clamps the same tightly between the legs so that itsadjustment is assured. By removing the wedge, the steel may be adjustedor reversed or turned upon its longitudinal axis so that different edgesmay be brought into operative engagement, it being understood that eachedge of the triangular bar is sharpened for the purpose described.

In operating the device, its lower end is placed against a table and thebody held at an angle while a knife blade is inserted between thebearing surface 2 and the steel 3 and drawn through in the usual manner.When it is desired to sharpen cleavers or the like, the tool is laidflat upon the table and the Cleaver used upon each bearing surface 11.By hooking the beveled ends 9 over Vva bottle cap and using the side ofthe clamp 12 as a fulcrum, the cap may be readily removed and the bottleopened.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion and the minor details ofconstruction, may be resorted to without departing from the principle orsacricing any of the advanlegs, a clamp for holding said legs in propertages of the invention as dened in the ap=` relative position, and aWedge engaging pended claim.
